I am the first, WE ARE ALL GOING TO DIE!
I blame SUV’s and Republican policies!

Where’s the KA-BOOM?
Exactly...If anything kills us ALL off, it will likely not result from anything originating on this planet.
Looking at the surface of the moon, I'd say the chances of a planet killing event eventually happening, are a real possibility. Remote yes, but a real possibility...
Too bad the site at the link did not choose to share at least one image with the rest of us.
“I was expecting an earth shattering Ka boom!” (Marvin the Martian)
No pictures! I think I know why.
They suppressed the images because they needed time to get into their personal bunkers before the pant-cr*pping terror hits home and the asteroid-induced riots begin.
But if you need a mental image in the meantime: just imagine a freeze-frame picture of a 100 mile-wide shotgun being fired at your head: that may help :0)
We don’t have enough stress.
Are they showing pictures in the kindergarten yet?
Here's a nice little animation:
It shows the five inner planets, together with the sea of asteroids they're moving through. The yellow dots are Earth crossing asteroids. The blue dots are asteroids that don't cross Earth's orbit. The Sun is at the center, of course, and the Earth is the third large orbiting dot out from the center. We're zipping around through some fairly congested space.
Will all of our windmills pull us out of the way? ;-)
I don't know how we keep missing Venus let alone all those yellow dots!
They don't have an actual count, only estimates, and probably won't have an actual count for a century or more, depending on technological advances. But it's got to be in the billions.
Then, of course, there are the mavericks, that zip through the Solar System from regions beyond and from every direction...
Perhaps the best defense against asteroids are other asteroids. Not with collisions, as most people would assume, but tethers.
Imagine you had a basketball. But tied to it is a softball. You throw the basketball in a straight line, but when the line connecting the two becomes taut, the softball is dragged along for the ride. But almost invariably, the softball does not go in the same direction as the basketball. The end result is that the flight of the basketball deviates from its straight line, pulled off course by the softball.
Now, were this a contest of masses, the softball would lose. But it isn’t. The softball continues to deviate the flight of the basketball, and in the scale of the distance traveled by an asteroid, this deviation can add up in a hurry.
The best bet to pull this off would be to ram the asteroid with a tunneling missile, connected to a tether which has already been connected to the smaller asteroid.
Not even close, except in the hysterical graphics that passes for science these days. Certainly not as congested as that graphic suggests. NOTHING IS TO SCALE!
Kids of all ages are not as dumb as we adults assume. The can certainly grasp the concept of relative distances and sizes.
I suggest these two sites as a start in understanding the distances and sizes involved :
Even the "science" satellite TV channels dumb things down to silliness. Not really necessary.
However, relatively speaking, the local environs of the inner solar system are indeed fairly congested. With nearly 10,000 known Near Earth Objects (almost 1,000 of them kilometer size or larger) and perhaps twice that many yet to be discovered, we should be paying attention.
That is great graphic
Of course we should be paying attention, but the only thing that the truly ignorant will remember is that kindergarten fuzzy OMG graphic.
Remember, they elected the Obama. Don't EVER overestimate the knowledge and judgement of the average "American."
I don't hyperventilate, except perhaps about ignorance.
As to "alarm," it kicks in when ignorant adults haven't a clue.
What is "relatively" congested?" Relative to the void between galaxies?
Is that something like "hope and change?"
